I had similar thoughts to the author, but I opted to just optimize those actions out of my life. If you only eat Huel(or any other powdered food thing) at home then pretty much everything described in the article is no longer an issue.

No more dealing with dishes, dishwashers, stray items on the table, boiling water etc. The only thing you need to worry about is cleaning your one huel cup which you can do right before you prepare your next shake.

I did it for a few years, eating breakfast + lunch at the office and then Huel for dinner or eating out at restaurant.
